Abstract
A bonding element, a bonding element matrix and composite materials with a wide range of attractive properties that may be optimized, including, but not limited to, mechanical properties, thermal properties, magnetic properties, optical properties and nuclear properties, as a result of a first layer and second layer structure or core, first layer, and second layer structure of the bonding elements, as well as methods for making the bonding elements and the corresponding ceramic and/or composite materials.
Claims14
A method of manufacturing a composite material, said method comprising:
- providing a precursor material that comprises a plurality of precursor particles, the precursor material having some degree of porosity;
- introducing a liquid solvent into the pores of the precursor material;
- and
- introducing a gaseous reactant into the pores of the precursor material, whereby the precursor particles are transformed into bonding elements,
- wherein the composite material comprises:
- a bonding matrix, and
- a filler material incorporated in the bonding matrix, the bonding matrix comprising a plurality of the bonding elements, each of the plurality of bonding elements comprising:
- a core;
- a silica-rich first layer at least partially covering a peripheral portion of the core;
- and
- a calcium carbonate and/or magnesium carbonate-rich second layer at least partially covering a peripheral portion of the first layer,
- wherein the core comprises at least one synthetic formulation having chemical elements M, Me, and O (oxygen) and/or OH group, M is an alkaline earth metal selected from calcium or magnesium, and Me is selected from a group of metals consisting of silicon, titanium, aluminum, phosphorous, vanadium, tungsten, molybdenum, gallium, manganese, zirconium, germanium, copper, niobium, cobalt, lead, iron, indium, arsenic and tantalum;
- and
- wherein the bonding matrix forms a hierarchic structure.
A method of making a bonding element, comprising:
- (i) providing a reactive precursor;
- (ii) transforming at least a portion of the reactive precursor to form a first layer over at least a portion of the non-transformed portion of the precursor and a second layer over at least a portion of the first layer, whereby a bonding element is formed;
- wherein the bonding element comprises:
- a core, which is the non-transformed portion of the precursor, and comprises at least one synthetic formulation having chemical elements M, Me, and O (oxygen) and/or OH group, M is an alkaline earth metal selected from calcium or magnesium, and Me is selected from a group of metals consisting of silicon, titanium, aluminum, phosphorous, vanadium, tungsten, molybdenum, gallium, manganese, zirconium, germanium, copper, niobium, cobalt, lead, iron, indium, arsenic and tantalum,
- wherein the first layer comprises a silica-rich layer, and
- wherein the second layer comprises a calcium carbonate and/or magnesium carbonate-rich layer.
